It was a pleasure to be inside the Olympic Stadium when Jonnie Peacock became more than just a sporting star at London 2012.

Aged 19, the Doddington sprinter clocked 10.90sec to take the men’s T44 100m gold medal in front of a passionate home crowd and become one of the main faces of Paralympic sport in this country in the process.

There was a long wait down in the mixed zone for Peacock to come and do his post-race interviews as a lap of honour, being reunited with his proud family and posing for photographs with an adoring public all had to be done.

But being there when a star was born was a special moment – and Peacock’s career has continued to soar ever since.

He followed up his London heroics to become a double Paralympic champion with victory in Rio last year, and now he is targeting further glory at the World Para Athletics Championships.

Being back in the arena where he burst onto the scene will be a big deal for Peacock, now 24, but his main focus is on staying ahead of the field and adding another gold medal to his collection.

“The world championships this year are back in the stadium where it kind of all began in 2012,” said Peacock. “Everything seems to be looking really good and training’s been going well.

“It feels like yesterday sometimes, but sometimes it feels like longer because there have been a lot of competitions in between.

“I think that feeling from 2012 will be back again. It was always going to be hard to beat and it’s probably going to be the biggest achievement I do.

“It all kind of fell into place and was just totally amazing. I don’t feel like anything will come up to that.

“But as a sporting achievement, Rio was always going to be harder as it’s a more competitive field now. It’s a different world to what it used to be, but I was lucky to get the job done in Rio.”

There had been speculation about Peacock’s big rival Richard Browne making a surprise appearance in London, but the American, who holds the world record of 10.61, has not been selected despite coming out of retirement and returning to the track.

However, Peacock knows there will be plenty of pressure on him to perform in Sunday’s event as a host of top-class sprinters are determined to spoil the party.

And working once more with coach Dan Pfaff, who was with him in 2012, has got him feeling full of confidence.

“It’s a very competitive field and there are some amazing guys involved, like Jarryd Wallace, Felix Streng and Arnu Fourie,” said Peacock.

“They will all want that title, so I guess it will come down to who delivers on the day.

“I feel stronger than I’ve ever been and the technique is becoming more consistent.

“I’m really pleased to have the coaches I’m working with now and it seems to be working well at the moment.”
